WINDOW ATTACHMENT.

Application filed May 14,

This invention relates to certain novel improvements in window attachments and more especially to a device for ralsing the lower end portion of a window curtain above an opening provided by raising'the lower window sash of a window construction and'has for its principal object the provision of an improved construction of this character which will be highly efficient in use and economical in manufacture.

The present invention constitutes an improvement over that disclosed in my prior application filed in the United States Patent Ofiic-e on or about the second day of February, 1926, Ser. No, 85,585. a

The present invention contemplates the provision of a curtain engaging member movable in engagement with a portion of a window curtain, by movement of a window sash of a window construction, in an upward direction to elevate the lower end portion of the window curtain above an opening provided by raising the lower window sash of the window construction.

Other objects will appear hereinafter.

The invention consistsin the novel combination and arrangement of parts to be hereinafter described and claimed.

The invention willbe best understood by reference to the accompanying drawings showing the preferred form ofconstruction, and in which: a

To accomplish the various objects of the present invention 1 provide guide plates 10 as shown in Figure 5, substantially U-shaped in cross-section, secured as at ll, Figs. '3

1926. Serial No. 109,174.

and 4:, to the lower window sash guide rails 12 of a window construction 13. These guide plates include longitudinally extendingrecesses 14 formed in the side walls 15 of the guide plates, as best illustrated in Fig. 3. a

The lower end portions of the bight portions 16 of the guide plates are cut away to provide passages 17 and curved inwardly as at 18, Fig. 4:, to provide rounded bearing edges 19. Mountedfor movement between the guide plates within the opposite wall portions 15 and 15" are carryingarms 20. These arms 20 carry at their inner end portions bearmg screws '21 rotatably supporting rollers 22 which are adapted to work in the recesses 14. The arms have arcuate slots 23 defined by lines 24 concentric with the axis of the bearing screws to define curved fingers 25,

Fig. 4. The outer end portions 26 of the I fingers 2 5 carry rollers 27 for the purpose of reducingfriction when the rollers work along the inner'wall surface 28 of the bight portions 16 of the guide plateslO.

Carriedby the corner portions 29 ofthe U lower window sash 30 0f the window construction 13 are operating arms 31 including laterally extending portions-32. These laterally extending portions 32 are slotted as at 33 and working within these slots are rotatable sleeves 34 carried by hearing screws 35in turn carried by the arms2O as best illustrated in'Figs. 5 and 6., The outer. end portions36'of the arms 20 carry a rod 37 adapted to move in engagement with the lower end portion 38 of the window curtain 39 for reasons hereinafter.understood.

The operation of the device thus far set forth is as follows:

When the window curtain 39 ishung in a straight line before the window structure 10 the arms 20 are disposed in their lowermost position, as best illustrated in 'Fig. 4, with the rod 37 in position to engage with the lower end portion 38 of the window curtain. When the arms are in this position the lower window sash30is likewise in its closed position. I

, When the window sash 30 is raised from its closed position, this raising movement of' the window .sash imparts movement to the operating arms 31. As these operating arms 31 move withthe window sash. 30 their laterally extending'portions 32 act upon the rotatable sleeves 34 and cause an outward and upward pivotal movement of the arms 20. As these arms 20 pivot in this direction the edge portions 18 of thearcuated', slots 30 work around and under the rounded edge portions 18. During this pivotal movement of the arms 20 the rod 37 is in contact with an adjacent portion of the window curtain 89 to fold its lower end, as shown in Figure 2. This pivotal movement of the arms'20 in this direction continues until the fingers are moved inwardly of the rounded edge portions 18 at which time the rotatable sleeves are disposed in engagement with the longitudinal edge portions 19 of thew-all portion 15. When the arms 20' have reached this position continued upward movement of the window sash urges the operating arms 31 to act upon the rotatable sleeves 34 and move the arms 20 in a vertical direction with the rollers 27 riding over the inner surfaces 28 of the bight portions of the guide plates and with the rotatable sleeves 3 1 bearing upon the edges 19. During this upward movement of the arms 20, through the ra1sing action of the sash 30, the rollers 22 work in the recesses 14 serving to guide the arms 20 in their vertical movement. The rollers 22 and screws 21provide a pivotal connection as well as a slidable connection between the arms 20 and the guide plates. 6

VVhen the window sash 30 is closed the arms 20 are caused to move downwardly in a vertical direction untilthe rollers 27 work outwardly over the rounded edge portions 18 at which time pivotal movement is urged to the arms 20. During this pivotal movement the rounded edge portions 18 pass into the arcuated slots 23 as best illustrated in Fig. 4. This latter pivotal movement of the arms 20 brings the rod 37 in position to permit the window curtain to hang in a v straight line before the window construction.

One feature of they present invention which enables me to manufacture the device at a economical cost resides in the manner in wh ch the guide plates are formed. As is apparent from the description herein and with reference to the accompanying drawings these guides plates are formed from a sheet of material bent substantially U- shaped to define the guide ways 16' within distance above the top sash rail 37' whereby when this rod 37 is in its lowermost position the same will not interfere with the raising of the lower window sash, said rod 37 being illustrated 1n this figure as well as Fig. 2 of *the drawin s in its u )ermost ivotal movement in a position readyfor vertical movement.

While I have illustrated and described the preferred form of construction for carrying my invention into effect, this is capable of variation and modification without depart, ing from the spirit of the invention. I, therefore, do not wish to be limited to the precise details of construction set forth, but desire to avail myself of such variations and modifications as come within the scopev of the appended claims.

Having thus set forth my invention, What I claim as new and desire to secure by Letters-Patent is: e

l. A window attachment including the comibnation with a window construction and a movable sash of the window construction, of substantially U shaped guide plates secured to the window construction and including passages at their lower end portions, supporting arms including slottedzend 'portions defining fingers movable longitudinally within the guide plates, the slots of the slots ted end portions being adapted to receive edge portions of the guide plates defining a passage when said supporting arms are pivoted in a certain direction and the fingers defined at said end portions being adapted for bearing relation with the bight portions of the U-shaped guide plates when the supporting arms are moved in a longitudinal. direction with respect to the guide plates for limiting pivotal movement of the supportin arms when moved in said direction, means providing a slidable pivotal connec tion between the supporting arms and'the guide plates, a curtain engaging member carried by the supporting arms, and means carried for movement with the window sash and operable upon the supporting arms for pivoting the supporting arms into and out of position for movement longitudinally of the guide plates. p
